Retrospective Analysis of the Results of Adjuvant Chemotherapy in Breast Cancer Patients with 10 or More Positive Nodes: Nonrandomized Comparison of Adriamycin-Containing Regimens / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: To evaluate the results of adriamycin-based adjuvant chemotherapy with or without high dose chemotherapy (HDC) with stem cell transplantation (SCT) in breast cancer with 10 or more positive axillary nodes. MATERIALS AND METHODS: Seventy-one breast cancer patients who had undergone surgery and had 10 or more positive axillary nodes were included in this study held between January 1997 and December 1999. The pathologic and clinical records were reviewed retrospectively. RESULTS: Twenty-nine patients were treated with adriamycin followed by 8 courses of CMF (group I); 22 patients received 4 courses of adriamycin and 7 patients received 3 courses of adriamycin. Twenty-six patients received median 6 courses of CAF (group II) and 16 patients underwent HDC and autologous SCT (group III). With a median follow-up of 27.1 months, relapses were observed in 24 patients (33.8%) and the 3-year disease-free survival (DFS) rate was 57.1%; group I/II 55.4%, and group III 62.7%. The three-year overall survival (OS) rate was 86.1%; group I/II 83.0%, group III 93.8%. There were no difference in the 3-year DFSs or in the OSs of group I and group II. However, patients who received only 3 courses of the sequential adriamycin in group I showed a significantly poorer 3-year OS than those that received 4 courses of adriamycin (42.9% vs. 95.5%). CONCLUSION: Our study shows that adriamycin-containing combination chemotherapy is as effective as HDC with SCT in patients with 10 or more positive axillary lymph nodes judging by 3-year DFS and OS, and shows that three courses of adriamycin seems to be inadequate.

Cytarabine Plus Daunorubicin or Idarubicin as Induction Chemotherapy for the Patients with De novo Acute Myelogenous Leukemia / 대한혈액학회지

BACKGROUND: The combination of cytarabine plus anthracycline has been considered standard chemotherapy for acute myelogenous leukemia (AML). We retrospectively analyzed the treatment results of the patients with de novo AML who received cytarabine plus daunorubicin or idarubicin as induction chemotherapy. METHODS: From 1989 to 1998, 149 patients with AML were included. For induction chemotherapy, the patients received cytarabine 100~ 200 mg/m2/day given by continuous 7-day in fusion plus either daunorubicin 40~45 mg/m2/ day (A+D) or idarubicin 12 mg/m2/day (A+I) administered for the first 3 days of treatment. We reviewed clinical records of the patients and analyzed the treatment results such as complete remission (CR) rate, disease free survival (DFS), and overall survival (OS). RESULTS: The CR rates were 67.1% (100 of 149); 69.3% (70 of 101) in A+D group and 62.5 % (30 of 48) in A+I group (P=0.409). The frequent reason of induction failure was resistant disease in A+D group (54.8%) and early death in A+I group (66.7%). The median DFS was 344 days; 344 days in A+D group and 314 days in A+I group. The median OS was 379 days; 389 days in A+D group and 379 days in A+I group. Age < or =60 years and allogeneic BMT as postremission therapy were independent favorable factors both for DFS and OS. AML M3 was favorable factor only for DFS. CONCLUSION: The combination of cytarabine plus daunorubicin or idarubicin was effective for the treatment of AML. We can not find significant difference in CR rate, disease free survival and overall survival between A+D and A+I group.
